Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622764, here are decompositions:

23 + 31622741 = 31622764
71 + 31622693 = 31622764
101 + 31622663 = 31622764
227 + 31622537 = 31622764
491 + 31622273 = 31622764
557 + 31622207 = 31622764
617 + 31622147 = 31622764
683 + 31622081 = 31622764

Showing the first eight; more decompositions exist.
